Before you even consider the Fiat, I hope you are aware that the engine needs to be removed in order to replace the cambelt...

And so your looking at around £1000 - £1500 for a proffesional job at a main garage, as most smaller ones wont even attempt it.

I know which one I would rather have between a Fiat and a Ford!

The Ford has endless supply of aftermarket parts available for performance increases, where as the Fiat doesnt. The Ford will hold more value too (im guessing your thinking of a cossie) and the Fiat will also be harder to sell on when the time comes. A good cossie wont loose much if any value as they are strong in the market for their age etc.
